ELEVATED RAILROAD.

SPECIFICATION forming part of Letters Iatent No. 397,519, dated February12, 1889.

Application filed October 30, 1883. Serial No. 289,518. (No model.)

To all whom it 711mg concern:

Be it known that 1, ROBERT F. ROBISON, a citizen of the United States,residing at Kansas City, in the county of \Vyan dotte and State ofKansas, have invented certain new and useful Improvements in ElevatedRailroads; and I declare the following to be a full, clear, and exactdescription of the invention, such will enable others skilled in the artto which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

The special object of the invention to improve elevated railroads, ashereinafter described, and pointed out. in the claims.

Figure]. of the drawings is a perspective view showing a section of theroad and its support with a suspended car. Fig. 2 is an end elevation ofa road-section, showing the relative position of the safeguards, tracks,truck, and caljilepulleys. Figs. 3 and l are detail views of the meansby which the truck is connected with the car.

In the drawings, A represents a section of my cable rmnl, suspended fromone arm, I), of the column 13 by the metallic straps (,which pass around[he said arm I: and are bolted to the track. A second track may besuspended from the other arm, I), of the column, so that the cars may berun in both directions. The track I.) is provided with the guard-rail E,which has the flange e passing to the outer side of the rails, so as tosupport the safetyguards F. The latter have at right angles thereto aliangaf, which hooks over the flange 6, so as to prevent an accident incase of the breakage of an axle or one of the metallic straps or bars G,which hold the subjacent car.

H is a superposed axle-spring, to which the car-supporting straps G areattached to take up jars and uneven motion 011 the axle I.

J J are the truck-wheels, having the annular flange j, which travels inthe groove formed by the tread and the guard-rail, while K are braceswhich connect and hold in vertical parallel relation the lattice-girdersL, so that the tracks cannot possibly spread apart.

M is the usual cable, passing between the pulleys N N, which are justfar enough apart to allow for the passage of the cable-grip betweenthem, and yet not far enough to permit the cable to drop down. The cablemay be operated by a stationary engine or any other preferred means, andany preferred grip may be employed.

Having thus described all that is necessary to a full understamling ofmy inventi0n,what

'I claim as new, and desire to protect by Letters Patent, is-

1. A rail for elevated railroads, consisting of the tread D, guardrailE, and flange e, to adapt it to be used as described.

9. The continuation, with an elevated track having the flanges cextending on the outside of the rails, of the safety-guards F, havingthe end iianges,f, as and for the purpose set forth.

3. The mmbination, with an elevated raillOittl-l'l'flflli, of the bracesK andlattice-girders, to prevent the track-rails from spreading apart,as set forth.

l. The combination, with an elevated railway-track, of the car providedwith straps F (l, the fm-mer overlying an outer flange of the track andthe latter supported on a superposed aXle-spring, as shown anddescribed.

In testimony whereof I allix my signature in presence of two witnesses.

ROBERT F. ROBISON'.
